Mikael's strategy
Fueling
Carbohydrate is the main fuel you burn when racing. Failing to fuel properly is a leading cause of underperformance in longer races.
Mikael proved himself to be an athlete who can consume much higher amounts of carbohydrates than the science suggests is possible, thus adding to the emerging anecdotal evidence suggesting athletes can consume more than 90g/h. This didn’t come without a little hiccup, however, as after consuming ~165g per hour(!) during the bike leg, Mikael felt quite bloated on the run as he clearly wasn’t able to absorb this high amount, despite being able to swallow it. Consequently, he sensibly backed off his fueling for a while to allow his stomach to settle, and the symptoms soon passed. Reducing the amount of Flow Gel he adds to his ‘fuel bottle’ on the bike would prevent him from overwhelming his stomach, whilst still allowing him to race hard and hit 100+g/h without GI discomfort in future.
Hydration
Taking on board an appropriate amount of fluid and sodium is essential to maintaining blood volume and supporting the cardiovascular effort needed to perform on race day.
Whilst the absolute amount of sodium and fluid consumed per hour is important, it’s critical to consider these in relation to each other. This is known as 'relative sodium concentration' and it’s expressed in milligrams per litre (mg/L). How much sodium you’re taking in per litre of fluid is more important than the absolute amount taken in per hour.
Sweat sodium concentration (mg/L) is largely genetically determined and remains relatively stable. Knowing how salty your sweat is enables you to replace a good proportion of your sweat losses, which can range from 200-2,000mg/L.
Whilst Mikael’s losses are on the moderate side, getting his hydration strategy right is still important if he wants to perform at his best.

Carbohydrates require water to be absorbed, so a mismatch between a lower fluid intake and a high carb intake may have further impaired absorption in the gut. Coupling a reduced carb intake with a slightly higher fluid consumption may double-down on combating his stomach discomfort.
Caffeine
Beyond the Three Levers of Performance (carb, sodium and fluid), caffeine is one of only a few substances that is proven to improve performance for most endurance athletes as it can help stave off mental and physical fatigue.
Mikael took a ‘little-and-often’ approach to his caffeine intake, so he was always reaping the associated benefits throughout the race. A coffee with breakfast kicked things off, followed by a PF 30 Caffeine Gel pre-race to peak his caffeine levels mid-swim. Then, by adding a couple more Caffeine Gels on the bike, Mikael ensured he fell within the general recommended guidelines for the stimulant during the race, and felt strong and focused throughout.

Data Confidence?
There is an adequate level of accuracy in the data collected and the numbers reported. The athlete manages to recall what they ate and drank including most specifics (brands flavours quantities plausible estimations of volumes). However there are estimations made within the data which affect the overall confidence level in the data reported.
